Voltage:220V
Size:85x73x22mm
Attention:
When the power supply is switched on, the power supply is connected with a limit
current of 4pcs 5W12 ohm high power resistors and a power amplifierr, and a few
seconds later, the delay line relay is switched on to 220V (the LED lamp on the board
is bright),Can reduce the impact of 220V voltage on large power transformer, large
capacity electrolysis, rectifier diode. For the use of the electronic tube power amplifier,
filament voltage has a slow pressurization process, can reduce the impact on the filament
voltage.
Note:
!Transformer using within 1000W.
!A few hundred watts of high power transformer, the primary resistance is small,
and some only a dozen ohm, the current impact of a large current, the power
of the light at the start of the home will be affected by the dark flash phenomenon.
